Previously, many of FF's internal data structures were contextual.
I hoped that this would improve performance. It hasn't done so yet, so I'm ripping them out for now. The non-contextual theory is considerably simpler.
I tested on the QF_FF benchmarks from our paper. Testbed: quad partition, 8GB, 5min. Both solved 605/864 benchmarks (with 6 that flipped).
Scatter plot:
Total solve time on commonly solved benchmarks decreases by about 23%.
@ajreynol : as a side effect, this should reduce sensitivity to term registration.
